UX Lead (Product & Growth)

Ruby Labs is a leading tech company that creates and operates innovative consumer products. We offer a diverse range of opportunities across the health, education, and entertainment industries. Our innovative teams are driving the future of consumer-led products, and we're always looking for passionate individuals to join us. Learn more about our story at: https://rubylabs.com/about-us/

We're building and scaling a high-growth D2C product used by hundreds of thousands of customers globally, and we're now entering a phase where UX is a core growth lever. We're adding new capabilities, expanding the product, and focused on improving retention, activation, and funnel performance — and we need a UX leader who can drive that.

We're looking for a UX Lead who is deeply technical, data-fluent, and design-strong. You'll own UX strategy, design quality, and the research practice — not as a support function, but as a core driver of product and business performance.

Today, design is mostly engineered directly in the frontend, and UX research lacks structure and direction. You will change that.

This is not a 9–5 role. It's a high-ownership, high-impact position for someone who wants to build systems, lead people, and directly influence growth metrics.

UX Strategy & Growth Impact

• Take full ownership of UX, design quality, and user journeys across the product.

• Turn UX into a measurable growth lever — directly improving activation, retention, and conversion.

• Work closely with Product and Growth to design and optimize funnels, onboarding, paywalls, and retention loops.

• Audit and continuously improve the end-to-end user journey — from acquisition through long-term retention.

Data & Analytics (Core Strength)

• Analyze product analytics independently — Mixpanel funnels, cohort analysis, retention curves, drop-off patterns.

• Connect UX decisions directly to business metrics — activation rate, retention curves, LTV, conversion.

• Define hypotheses, experiments, and success metrics for every UX initiative.

• Use session recordings (Clarity, FullStory, Hotjar), heatmaps, and behavioral data to identify friction points.

• Proactively request and define new analytics instrumentation and reporting needs with the data team.

• Validate UX changes through A/B testing (GrowthBook or similar) — hypothesis, implementation, result analysis.

Design Leadership

• Define, enforce, and evolve a clear, scalable design system (implemented directly in frontend, not Figma-first).

• Lead and direct designers and frontend engineers involved in UI/UX work — set the definition of done.

• Set the visual and interaction quality bar across the product.

UX Research

• Establish a structured research practice — define priorities, run interviews, surveys, and usability tests.

• Translate raw research into prioritized, actionable product decisions.

• Direct and level up the existing UX researcher on the team — provide structure, frameworks, and clear priorities.

Core Strengths (Must Have)

Data & Analytics

• Strong, hands-on ability to analyze product data independently — you pull your own funnels, you don't wait for reports.

• Deep experience with Mixpanel, GA4, Amplitude, or similar product analytics tools.

• Ability to read cohort and retention data, identify patterns, and build hypotheses from raw numbers.

• Experience designing and running A/B tests (GrowthBook, Optimizely, or similar) end-to-end.

Retention & Growth Expertise

• Demonstrated experience driving measurable improvements in retention, activation, or LTV.

• Strong understanding of conversion funnels, retention loops, and user behavior at scale.

• Background in CRO (conversion rate optimization) or growth-driven design.

Design Leadership

• Strong design background with a portfolio of conversion-oriented, data-validated work.

• Experience leading or managing designers — you've set direction, reviewed work, and raised team quality.

• Ability to define and maintain a consistent, high-quality design system.

• Comfortable working in environments where design is implemented directly in frontend (no Figma-first culture).

UX Research

• Proven ability to collect both qualitative and quantitative user insights.

• Experience designing and running user interviews, surveys, and research frameworks.

• Ability to translate research into clear, actionable product decisions.

Experience & Mindset

• 5–8+ years in UX, Product Design, or design leadership, ideally in D2C, SaaS, or consumer digital products.

• Experience working in fast-paced, growth-oriented environments with daily or near-daily releases.

• Systems thinker — designs scalable patterns, not one-off screens.

• Clear communicator — explains the why behind every design decision with data.

• Strong ownership mindset — owns outcomes, not output.

• Experience in LegalTech, document tools, or utility products.

• Familiarity with TailwindCSS, React/Next.js component implementations — you can review frontend code, not just spec it.

• Experience working in engineering-led teams without a separate design org.

• Exposure to PDF-based or form-heavy UX flows.

• You will define how UX drives growth, retention, and monetization at scale.

• You will build the design and research foundation for multiple products.

• You will work directly with product leadership and influence key business decisions.

• You will turn UX from a weak point into a competitive advantage.

• High pace, high ownership, high standards.

• Not a role for a "design-only" mindset — this is about impact on business metrics.

• We expect people to take initiative, move fast, and continuously improve the product.

• Fully remote.

• Competitive remuneration + performance-based bonus upside.

• Real leadership scope — you'll shape both the product and the team.

• Direct influence on a product used by hundreds of thousands of users — every UX improvement is measurable.
